I would like to develop a search system based on OSM data to retrieve objects that co-occur in space with queries like “show all schools that are within 100 m from parks”, “find all restaurants near a lake”, “residential streets far from pubs".
I think that this kind of search would be useful to many users in a variety of applications, e.g., real estate, tourism, etc., and at the moment OSM (or Google/Bing/etc) does not offer this functionality.
I have some students/programmers who could develop it as part of their studies. I’m quite new to OSM, so I would like to ask you for advise on how to proceed. What would you recommend to do to develop this in the right way, maximizing its usefulness to the OSM community and re-use of existing code? Is there some cloud infrastructure to develop this kind of apps?
